3. Turn the thermostat knob G to setting 4.

                        When the refrigerator is equipped for 110 volts and 12 volt operation the
                         turning movement of the knob A should be made as follows:
                         In gas OFF position the knob is pressed and turned clockwise to the
                         12 volt position, If 110 volt operation is desired press once more and
                         continue the clockwise turning to the 110 volt position marked

                   LEVELING

             In the boiler of the cooling unit, ammonia vapor is distilled from an ammonia-water
             mixture and carried to the finned condenser where it liquefies. The liquid f                 to
             the evaporator inside the cabinet where it creates cold by evaporating into a
             circulating flow of hydrogen gas. If the evaporator is not level the liquid readily
             accumulates forming pockets              can impair the gas circulation or block it com-
             pletely, in which case, of course, cooling will

             When the vehicle is stationary it must be leveled to be comfortable to live in. If
             the refrigerator is properly installed, i.e. the ice-tray compartment shelf is
             parallel with the floor, the refrigerator will operate properly, To check this, a
             bubble level (see Fig. 73) is supplied with the refrigerator, The level should be
             placed on the ice-tray compartment shelf and the
             position of the bubble observed (if necessary,
             with the aid of a small mirror), Adjust the position
             of the vehicle so that the bubble is in the center
             ring of the level.

              When the vehicle is on tow, the continuous rolling and pitching movement                 not
              affect the refrigerator as long as the movement passes either side of level but
             when the vehicle is temporarily parked, the sensitivity of the refrigerator should
              be remembered,




             1.   When the temperature control (thermostat) is set at a higher number, refrige-
                  rating effect will be increased, This            tend to lover the temperature in the
                  freezing compartment and in the food storage compartment.

                        the temperature control is set at a lower number, refrigerating effect will
                  be reduced.

                        the temperature control is set at mid-dial position, medium refrigerating
                  effect will be produced.

             2.   The position of the temperature control should depend upon the refrigerator
                  load.       the food load is heavy, turn the temperature control to a higher
                  number .   higher setting of the temperature control will be required in summer
                  than in winter.

                  The setting of the temperature control determines the action of the thermostat
                  in relation to freezing compartment temperatures,
                  THE              CAPILWRY TUBE

             On the fresh food evaporator is a sleeve in which the end
             of the thermosta: capillary tubing must be inserted. Check
              that the capillary tube is firmly in place, If the capillary
              tube is not properly inserted in its sleeve             Fig.
                  burner will operate continuously at maximum flame.
              It will cause too low cabinet temperatures.                                     F i g .
